Log message:
229. XFree86 loader enhancments:
- Per-module export symbol lists.
- Improved symbol hash.
- A mechanism for specifying the scope of symbols.
- Keep track of relocations, and undo them when they become unresolved
on module unload, and recalculate them when they change on module
load.
- Check relocations on each module load/unload, ensuring that function
references that are unresolved at any time are always mapped to the
catch-all function preventing calls into nowhere.
- Efficient handling of invariant relocations.
- Cleanup/update the memleak stack trace code, and print a stack
trace when an unresolved function is called or when XFree86 aborts.
- Update the catch-all function to identify the unresolved function.
- Read the XFree86 executable's symbol table in order to get the
most useful stack traces, and use dladdr(), where available,
for shared library references.
- Cleanup and unify debug messages for the loader components.
- Allow for module-instance-specific referenced and required
symbols lists, so that a module's requirements can be removed
when it is unloaded.
- Update the ati driver to make use of some of the new loader
functionality.
- General loader cleanups, including removing some redundancies.
- Don't build the coff loader on platforms that it doesn't support.
